Hugging Face, ClawHub Abused for Malware Distribution

Threat actors are using trojanized shared files to distribute malware via AI distribution platforms such as Hugging Face and ClawHub, Acronis reports. The attacks do not compromise AI agents, but rely on social engineering to trick users into downloading files containing malicious code designed to execute commands, fetch payloads, and install hidden dependencies. Both platforms allow developers to easily share code, and threat actors are abusing users' trust in them for nefarious purposes. READ MORE...
